Water vapor permeabilityGlass transitionEdible films are thin materials based on a biopolymer. The objectives of this work were to determine the water vapor permeability and the mechanical and thermal properties of edible films based on bovine hide and pigskin gelatins. These films were prepared with...
This paper deals with water vapor transmission and thermal properties of various warp knitted spacer fabrics. In this work, thermal and water vapor permeability of different spacer fabrics have been evaluated by varying the structure, areal density, thickness, type of raw materials, etc. The air ...
The state of adsorbed water and water vapor interaction on the fiber surface were studied by simultaneous thermal analysis (TGA-DSC) measurement. The percentage of bound and unbound water formation at low and high humidity had a profound effect on the thermal performance of fibers. It can ...
For a multi-layer wall, thermal properties are expressed by thermal transmittance [42], or U-value, which is the heat flow that passes through a unit area of a complex component or inhomogeneous material due to a temperature gradient equal to 1 K; it is expressed in W/m2 K. The inverse...
*Reference to the 'balance' of a composition does not guarantee this is exclusively of the element mentioned but that it predominates and others are present only in minimal quantities. Physical and Thermal Properties Physical and thermal properties of INCONEL alloy N06230 are reported in Tables 2...
than that of the latter, due to the adjustment of water vapor content to the temperature variation of the atmosphere.According to our estimate, a doubling of the COcontent in the atmosphere has the effect of raising the temperature of the atmosphere (whose relative humidity is fixed) by about...
The s-BAs can support uniaxial strains above 500%, similar to that of a homogeneous elastomer. These results indicate that the overall BAs/elastomer composite still remains good mechanical compliance. The mechanical properties are also evaluated using the finite element method by treating the s-BAs...
However, the mechanical properties of inverse vulcanized polymers are currently underdeveloped. If this kind of material is to be widely used in some scenarios to replace some traditional plastics, it is necessary to make them with appropriate thermal and mechanical properties that meet basic ...
The selection of thermal insulation material is based on its thermal conductivity, thermal mass, temperature of indoor and outdoor spaces, durability, cost, and other factors. The thermo-physical properties of the materials used in the building envelope strongly affect the heating or cooling energy ...
